AN INCREASE OF PROTEIN WHEN LESS THAN 2 LBS. AND MORD THAN 
1.6 LBS. 
One hundred and twenty-seven records cover periods when sucha 
change was made. There was also on the average a slight in- 
crease in the total nutrients. The average data are given in 
Table XXIX. The milk flow diminished scarcely any. There 
was a moderate loss in live weight before and a slow gain after 
the change of ration. 
With little change in amount of nutrients —When the amount of 
nutrients was but little changed in 53 instances there followed 
about the normal falling off in milk production (A, Table XXIX). 
Under the rations fed there was a moderate loss in live weight. 
With an increase of total nutrients—When there was an in- 
crease of the total nutrients in 65 instances there followed an 
appreciable increase in the milk production, and the cost of pro- 
duction was somewhat higher. There was some loss in live
